Hello We use FIO to check the eMMC storage on our embedded boards. This works great for our modules that have >= 1GB RAM but on all lower-memory ones (<= 512MB) the OOM killer always kills FIO. I can hook up a swap which helps but is just painfully slow. I played with the settings mem, bs, iodepth and size but cannot achieve a configuration that works on low-memory embedded systems. Can anyone guide me how I can make this work? Best Regards, Philippe
